Planning Future Heterogeneous Wireless Networks
Jijun Luo, Xuemin Huang · PIERS Online · 2005
In this paper, based on the analyzed emerging challenges encountered by the future radio network, we focus on several candidate techniques targeting at a more spectrum-efficient and cost-effective solution. Among them, spectrum management is one special topic covering fields of technique, regulation and politics. We point out the high tendency of spectrum liberation in terms of spectrum allocation for services and radio technologies even between different network providers. In the network planning topic, we address a number of solutions w.r.t. some typical dominating factors. A solution reducing the risk of high expenditure in conjunction with the flexibility of spectrum management is also given. To further enhance the efficiency, advanced radio resource management allowing interworking among heterogeneous radio technologies is also presented. I.
